Magic: The Gathering publisher Wizards of the Coast has filed a lawsuit against Cryptozoic Entertainment and Hex Entertainment alleging that the companies' online card gameHex: Shards of Fateis a Magic clone.

Here's the Wizards of the Coast statement, which was posted on the company's website today:

Today Wizards of the Coast LLC, a subsidiary of Hasbro, Inc. (NASDAQ: HAS), filed a lawsuit in the United States District Court for the Western District of Washington against Cryptozoic Entertainment, LLC and its alter ego, Hex Entertainment, LLC (collectively, "Cryptozoic"), for willful infringement of intellectual property rights.

Cryptozoic develops and publishes the digital trading card game, Hex: Shards of Fate, a clone of the world famous tabletop collectable trading card game, Magic: The Gathering®, and its digital expressions, Magic Online® and the Magic: The Gathering – Duels of the Planeswalkers® franchise.

"Hasbro and Wizards of the Coast vigorously protect our intellectual property. This infringement suit against Cryptozoic demonstrates that while we appreciate a robust and thriving trading card game industry, we will not permit the misappropriation of our intellectual property" said Barbara Finigan, Senior Vice President and General Counsel of Hasbro. "We attempted to resolve this issue, but Cryptozoic was unwilling to settle the matter."

The suit includes claims for copyright, patent and trade dress infringement.
